Mass Additions

If we populate the Add_to_Asset_id filed, in the FA_MASS_ADDITIONS table, what would the end user have to do in the preparation of the Mass Addition line in order for it to be included in the cost of the existing asset?  Would they simply have to change the queue to POST and the system will automatically change it to COST ADJUSTMENT?  Would they need to click on the ADD to ASSET button??

Thanks
